Spending Poetics on tokens for old content that have their Ultimate

[Hasrat]

I just spend 2000 poetics levelling desynthesis.

Is there any great point to that now that desynth never fails? I suppose it's good if you know you can get important/useful items out of it if you're crafting with those. Upping your "rare item" chance seems like it would still fall into the same reasoning.

As for selling something for gil, personally have little use for the stuff myself. Probably spend gil less often than tomes.
